我最近安装了 Ubuntu Server 12.04 LTS。几天后，我尝试进行第一次更新，遇到了一个问题，虽然这不是什么新鲜事，但我认为对我来说，这个问题有点突出。
于是，我尝试安装一个新的内核版本。系统说有错误，有依赖项，所以它建议尝试一下apt-get -f install。输出：
xxx@lab103-server:~$ sudo apt-get -f install

如您所见，某处没有足够的空间。关于空间：

我的系统信息：

其他帖子建议在安装新内核之前删除旧内核以释放一些空间，但就我而言，我只有一个内核版本！
lozovskiy@lab103-server:~$ dpkg -l | grep linux-image
ii linux-image-3.2.0-29-generic 3.2.0-29.46 Linux kernel image for version 3.2.0 on 64 bit x86 SMP

我害怕删除它们，所以我认为另一个解决方案是首先增加空间/boot？或者是/？哪一个以及如何增加？
答案1
可以删除正在运行的内核，但我不建议这样做。我会重新安装并确保有足够的空间。但是你真的需要升级内核吗？
您使用的是哪个引导程序？使用 GNU Grub，内核位于何处并不重要，只要 Grub 可以读取分区，您就可以从 GNU Grub 控制台加载它。
如果您想要调整大小而不是重新安装，请尝试从 Live CD 启动并运行gparted。请参阅为什么我在尝试使用 gparted 修改的分区旁边看到一个锁？
